Overlap Distribution of the Three-Dimensional Ising Model
We study the Parisi overlap probability density P_L(q) for the
three-dimensional Ising ferromagnet by means of Monte Carlo (MC) simulations.
At the critical point P_L(q) is peaked around q=0 in contrast with the double
peaked magnetic probability density. We give particular attention to the tails
of the overlap distribution at the critical point, which we control over up to
500 orders of magnitude by using the multi-overlap MC algorithm. Below the
critical temperature interface tension estimates from the overlap probability
density are given and their approach to the infinite volume limit appears to be
smoother than for estimates from the magnetization.Comment: 7 pages, RevTex, 9 Postscript figure

О спектре сингулярных возмущений полупериодических операторов
Досліджено властивості заданих у комплексному сепарабельному гільбертовому просторі L^2(0,1) операторів (D^2−)^s+V(x), s що належить (1/2,∞), де D^2−=−d^2/dx^2 — диференціальний оператор з напівперіодичними граничними умовами, а 1-періодична узагальнена функція V(x) належить негативному простору Соболєва H^−sα +, α що належить [0,1]. Дано опис якісних спектральних властивостей таких операторів, знайдено многочленні асимптотичні формули для їх власних значень при s що належить (1,∞) як в самоспряженому випадку, так і в несамоспряженому.We investigate properties of the operators (D^2−)^s+V(x), s belongs (1/2,∞), given in the complex separable Hilbert space L^2(0,1), where D^2−=−d^2/dx^2 is a differential operator subject to semiperiodic boundary conditions, and the 1-periodic distribution V(x) is in the negative Sobolev space H^−sα +, α belongs [0,1]. We describe qualitative spectral properties of the operators and find polynomial asymptotic formulae for their eigenvalues for s belongs (1,∞) in a self-adjoint case and in a non-self-adjoint one
Variance of the decay intensity of superdeformed bands
We present analytic formulae for the energy average and variance of the
intraband decay intensity of a superdeformed band.Comment: 4 pages, 2 figures, presented at the VIII International Conference on
